Letters Patent No. 62,169, dated February 19, 1867.

enorme RANGE.

l TO ALL WHOM 1T MAY CONCERN:

Be it known 'that I, THOMAS C. WALTER, of San Francisco, San Francisco county, State of California, have invented certain new and useful improvements in Cooking Ranges; and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the artor scicncetc which it most nearly apperta'ins to make and use my said invention without further invention or experiment.

The nature of my invention is to provide a cooking range of such construction that either wood, coke, or bituminous coal may be used; if bituminous coal, it will be 'coked in the grate. It has also ovens so arranged that by, means of dampers the heat can bc directed around either or both. Thecentral compartment is lined with either porcelain or any substancc to retain and 'redect the heat, and is situated directly over the grate, so

that, when desirable, the heat may be made to pass directly through it, and all cooking be done by the direct action of the heat instead of its being radiated, as in the oase of ordinary close ovens.

A register projects in front of the range near the door, having a damper, and may supply air for combustion as desired, either in thc ordinary manner, or by feed pipes directly from the open air, and with the damper below the grate serves to form the coke. This register may also support an apparatus for cooking by means ofthe radiated heat from the front of the range when necessary. In order to more fully explain the operation of my invention, reference is had to the drawings forming a part of this specification, in whichy Figure l represents a horizontal `sectional view taken through x 9:, showing the grate and a portion of the ilues leading therefrom.

Figure 2 is a vertical sectional view taken in the line 3/ y, showing the relative. position of the tlues and ovens, and the grate in front. l

Figure 3 is a perspective View of the whole range. y

Figure 4 is a transverse sectional view taken through the line s z, showing. the relative positions of the parts in iig. 2.

Similar letters of reference indicate like parts in each of the figures. i

'A is the receptacle for the fuel, `which lies upon the grate cZ. Below this is the ash-pit. B is a damper or movable bottom for the furnace, which may be closed when the fuel is sufficiently consumed, so that a. thoroughly ignited mass of coal remains, which then consumes slowly. In using the bituminous coal, the false bottom or damper B is closed so as to coke it, also to rarefy the air before combustion takes pla'ce, and may be'applied to other furnaces. This bottom also serves-to keep the tine coal from being lost or scattered into the ash-pit. In using wood, by closing the bottom B, the wood will be formed into' charcoal, and may he used in cooking without making smoke. C is the central compartment, situated directly over the grate, and connecting it by means of a cover, S, which may be removed so as to allow the heat toppass directly through the compartment, as indicated by the red arrows c cc. The dampers I I, shown at the top of iig. 3, connect C with the chimney M, so that all gases or odors evolved from the fire or the cooking will be carried oil` immediately.` K K are ilues connecting with the furnace A, by openings at its sides, and so connected with ilues F and F', and h i, that by dempers c ethe heat may pass through either F or F, or both, and thus through the iiue Gr, around the oven D, Vthrough ff, as shown by the black arrows a a a, or the damper g in the iiue G, may be closed, so that all the heat will pass through the tine It lz, around the oven E, as shown by yellow arrows b b b. The heat may .then either pass directly to the chimney, or, by closing the damper z', be made to pass around tll'e oven D. J is a damper to regulate the draught around the oven D. N, the register containing the regulating damper m. Upon N may be set a baker to cook meats by the heat radiated from the furnace front, o.

In using my range, the fire is kindled in the furnace A. While the fire is burning down' so that the coal has become thoroughlyignited, or at any other desired time, the ovens E and D, one or both, may be used. If necessary more ovens may be added, similar to E, or the range may be constructed with only the oven D. When it is desired to use the compartment C, the damper B is opened, the dampers g and e' are closed, and the top removed from the furnace so that the heat all passes through-C to the chimney. The interior of C is lined -wth iron plate and porcelain, or any substance to reiiect the heat and make it suilicientfor cooking. There are bars across from side to4 side, to support whatever may bc placed within, and the doors pp maybe closed. All products of the fire or cooking pass` directly through the dampers I I,V and thus many different kinds may be cooked at the same time Without losing their distinguishing Havor, or becoming impregnated with that of the others. This compartment is to be used only when the fire is clear, with but little smoke, and in the use of bituminous coal it is coked rst by closing the damper B. The openings r r r ure to be used when needed. The advantages to be gained by the use of my range are, an economy in the use of the heat, and principally the benefit derived from cooking with the direct heat of the fire, in the use ofthe compartment C.4 v

Having thus described my invention, what claim, and desire to secure by Letters Patent, is-

1. The furnace A., und the ovens D and E, with the lues K, F, f, und 7L, with their regulating dempers, constructed as described for the purposeset forth.

2. The compartment C, in combination with the furnace A, arranged as described.

3. The register N, with the damper m, and the damper B, combined with the furnace A, as described.

4. The arrangement of the furnace A, with the damper B, and the register N, the ovens- D and E, with their dues and the compartment; C, all operating together, substantially as and for the purpose set forth.

In Witness whereof I have hereunto set my hand and seal this 9th day of August, 1866.
